Be it known that I, GEORGE M. COPEIJAND, of'Brooklyn, Kings county, State oi' New York, have invented u new andI useful Combination of Air and Steam Jets for the more Rapid and Perfect Combustion of Fuel; und I do hereby declare that the following is a full, clear, and exact description thereof, which willenable others skilled in the nrt tomake and use the sume, reference being had to the accompanying drawing, forming part of this specification, inwliich- Figure 1 is a top view ef asteam' boiler with my improved apparatus attached.

Figure 2 is a sidcview of the same partly in section through the line :c 2:, iig. l.

Similar letters of reference indicate like parts.

My invention has for its object to furnish au improved means for increasing the draught cfu boiler, fui-once, or other lire-place, making the combustion of the fuel more rapid and perfect, and'thus increasing the effectiveness of the iire. And it consists, first, in the combination of an air and steam jet or jets with cach other, :ind

their introduction into asmokc tine, chimney, or other passage; second, in the combination-of an air pipe, single or branched, and a steam `pipe-.or pipes with eachother and with the smoke tlnc or chimney, or other .passage wey inwhich they are placed. i f l -L i I A istile boiler, about the oonstruetion'of which there isnothing new; B is the smoke box, and Ctho smoke flue; D is the air pipe passing up mmthe interior of the tine C, and parallel therewith. This pipe I prei'ertc place in the middle of the ue C, so that the jet therefrom may affect the smoke or nir in all parts of the tlue equally. The pipe D is bent and passes ont through the sido of the flue C, and may be a single pipe terminating in the room in which his boiler. is placed, or in any other place, or it may be mmlewith branches di d2 d, lending to lother rooms, or one of them may lead ont oi' doors, sothat the air to supply the jet may be token from nny desired place. These pipes or branches are all furnished with dempers,- E, which may be all closed except the one leading to the place from which it is desired to take the air to supply the jet; F is .n steam pipe, loading from the steam chest of the boiler A, passing in through the wall of the ue C, and through the woll of the air pipe D, and up in a direction parallel therewith. The pipe F isfnrnished with a valve, G, by means oi' which the passage of steam through it may be checked onregulated as desired. Several steam pipes may be introduced into the air pipe D, so as to distribute the steam jets through the said pipe. In using the apparatus, the demper in the pipe D, or in the brunch of the pipe D, leading to the place from which it is desiredto take the air, is opened, allowing s. streaml of air to pass through the said pipe into the ilne C. The vulve in the steam pipe F is then opened, allowing a jet of steam to be projected into the pipe D,Vin the direction of its'lcngth. This tends to produce n. vacuum in the part of the pipe'D immediately below the point nt' which the jet of steam is introduced, which causes u strong current of air to How in to supply its piace. 'Tho combined air and steam jet projectcd into the flue CI produces the same effect therein, producing a strong draught through the tire-chamber, causing a more rapid and more perfect combustion of the fuel, and thereby greatly increasing the eectirc force of the fire. l

I claimssnew, and desire to secure by Letters Petentv 1. The combination of an air und steam jet or jets with eachother, and their introduction into a chimney,

smoke ue, or other passage way, substantially as herein described and for the purpose set forth.

2. The combination of au air pipev D, single or branched, and the steam pipe or pipes F, with each other, und with the smoke flue, chimney, or other passage way in which they are placed,substuntially as herein described and for the purpose set forth.
